In order to study the influence of air pollution control devices(APCDs）on the condensable particulate matter(CPM）emission characteristics from an ultra-low emission coal-fired power plants in China,the EPA Method 202A recommended by the U.S. Environmental Protection Agency was used to simultaneously sample the flue gas before and after the wet flue gas desulphurization(WFGD）and after the wet electrostatic precipitator(WESP). Then the migration,transformation and emission characteristics of CPM in the flue gas were obtained based on sample analysis. Through further data analysis,the migration and transformation process of CPM in APCDs and the synergistic removal effect of existing APCDs on CPM in the power plant were studied. The results indicate that CPM dominates the particulate emission in the flue gas after ESP. The mass concentrations of CPM at the WFGD inlet,WFGD outlet and WESP outlet are 24.07,12.71 and 7.72 mg/Nm³ respectively,while the proportions in TPM are 61.83%,53.34% and 76.06% respectively. With the flue gas flow,the proportion of the inorganic composition of CPM gradually decreases,from 69.38% at the WFGD inlet to 54.40% at the WESP outlet. The inorganic part of CPM is mainly composed of acid radical anions such as SO₂^-4,NO^-3 and Cl^-,and the mass concentration of SO₂^-4 is the highest. The removal efficiency of CPM by WFGD and WESP is 47.20% and 39.26%,respectively. The combined removal efficiency of CPM by WFGD and WESP is 67.93%. The results can provide a good reference to the CPM emission and control from an ultra-low emission coal-fired power plant.
